The railway services some well-known sights and locations such as Louisiana Museum of Modern Art in Humlebæk, Kronborg Castle in Elsinore, and Dyrehavsbakken in Klampenborg.

The North Line was built though Helsingør in 1864 and in 1863 the connection between Copenhagen and Klampenborg Station as a sort of daytrip and tourist route.

In 1890 the Minister of the Interior, Hans Peter Ingerslev (Conservative People's Party), a proposition of a state railway between Klampenborg and Helsingør, but it went four years of discussion and negotiations before the surveyors could stop their work and the construction workers enter the field.

Because of rules decided by the Ministry of War, the railway had to go in a large curve out over the lakes to Nørrebro and onwards towards the Øresund Coast at Hellerup.

DSBFirst won this bid due to their plan of introducing 7-Eleven to the majority of stations, keeping the current system of permanently staffed trains, and promising better scheduling.
